MS3X testing with JimStim - No RPM Signal

[thev's]

Hi, newbie here, happy to have built me MS3X, now into the testing phase. Good news - TPS, MAT, O2, CLT all work nicely, however I don't seem to be able to get RPM

I have

1. Confirmed using led test I can get RPM on the JimStim
2. On the JimStim - Jumpered Primary Tach for VR signal, Jumpered 5V to Pullup on 2 and P, set dipswitch on for 2,3,6.
3. On the TS ignition control - setup spark mode = miata 99-05

Not sure what to try next, any help/ideas welcomed. Thanks very much in advance for any suggestions

have you tried to set the pullup for 12v?
